Limited geochemical and ground geophysical surveys were carried out to the south and east of the main Prince Alfred mine workings, seeking buried extensions to the known orebody. 5 lines of IP measurements, plus soil and rock chip samples taken along...

Appraisal of the historic Spring Creek copper mine area, located approximately 8 miles south-southeast of the township of Wilmington, commenced with an IP survey of the immediate mine site, where the lode outcrops over some 20 feet in weathered...

Exploration for possible economic hydrothermal / replacement style copper deposits within two known mineralised areas on the northern margin of the Blinman Diapir comprised geological mapping of the stratigraphic / structural setting of accessible...

Geological reconnaissance mapping, plus soil, stream sediment and rock chip geochemical sampling, and limited ground magnetic surveys over several mined prospects in the Western River area of Kangaroo Island, failed to disclose indications of an...

A study has been made on the feasibility of using magnesite ore mined from BHP leases in the Port Germein Gorge to produce up to 50 tons per day of high grade magnesia (MgO) using the Bicarbonate Process (ref. US Bureau of Mines, 1946) at the...

Exploration and mining carried out at the mines so far is not enough to allow a full assessment of the mineralised area. The deeper old workings are now inaccessible, and there is no other evidence of primary sulphide ore. Nickel and bismuth assay...

Initial renewed company exploratory work at the Wheal Ellen mine locality has included surveying of old workings, aerial photo interpretation and ground checking, reconnaissance soil and bedrock sampling, and extensive IP surveying which defined many...

At the joint request of the South Australian Department of Mines and Broken Hill South Ltd, Amdel was engaged to evaluate the possibilities of treating remnant ore known to exist both underground and in dumps at the Kapunda mine (where an estimated 6...

Exploration for possible lode extensions of stratiform base metal mineralisation worked at the historic Baratta - Eukaby mines has comprised gridding, geological mapping, costeaning, rock chip sampling, and exploratory inclined percussion/diamond core...

Several minor occurrences of copper sulphide mineralisation associated with diapirism and igneous activity centred on the Mount Remarkable Fault were investigated by a literature survey of salient features and of past exploration methods used. It was...

A review of past exploration carried out in the vicinity of the Arkaba Diapir has concluded that the potential for finding near-surface economic metal mineralisation is slight, although the use of modern deeply penetrating geophysical techniques such...

Continuing exploration of the area near Olary, primarily for undiscovered near-surface lodes of economic copper and silver minerals, has involved mainly a close inspection of several old abandoned mines and limited surface geochemical sampling of...

A diamond drilling programme of 3 holes totalling 1284 feet of penetration was carried out on the Baratta Mining Field to test two IP anomalous zones trending easterly and lying approximately 10,000 feet apart. The objectives were to investigate the...

Close examination of large scale apparent folds in the vicinity of Wheal Ellen has led to the conclusion that apparent folds can be produced by a combination of jointing (shearing) and topography. Thus, apart from fault trace offsets, no importance...

Follow-up work to previous, Department of Mines and company geological mapping, ground geophysical and geochemical surveys and wagon drilling in the vicinity of abandoned copper mines on the Mount Lyndhurst Diapir, has consisted only of limited...

Regional stream sediment sampling conducted over an area of historically prospective ?Archaean, Proterozoic and Palaeozoic rocks in the Mount Painter - Mount Babbage - Mount Livingstone - Yudnamutana area did not reveal any base or precious metal...

Reconnaisance and detailed geochemical surveys, plus limited diamond drilling at the Baratta mine (2 holes for 480 feet), failed to find any extensions to known but worked-out near surface Cu-Pb-Zn lodes. It was concluded that only a small area...

A re-investigation of the remnant mineralisation potential of the Ediacara Mineral Field has involved a review of SA Department of Mines' (SADM) diamond drillhole data, the selective re-sampling of diamond drill core intervals for assay, detailed...

Possibly prospective copper mineral occurrences in the vicinity of Beltana were investigated by conducting part of a multi-licence aerial survey over them, and by researching all of the existing information on the local geology. An extensive desktop...
